PAGE NO.: 9 OF 9 POST REFLOW, CLEANING CONDITIONS A 5% saponifier combined with water during wash. For the ultrasonic process water temperature should be at 50 C and board should be submerged for a minimum of one minute in the solutions, then rinse and dry. For in-line washing, the temperature of the water sprayed should be at 110 C, rinse and drying is done inline. Warning: Application Limitations for PESD0402-140.
